Can you hear me?

May 5, 2009Can a cuttlefish hear?
A magnetic resonance image (MRI) reveals the internal anatomy of a
cuttlefish (Sepiaofficinalis). WHOI postdoctoral scholar Aran Mooney, senior scientist Darlene Ketten, and scan technologist Julie Arruda are
working with scientists at the Marine Biological Laboratory (MBL), Roger Hanlon, Lydia Mathger and Justine
Allen to determine how cuttlefish and squid detect sound in water. The
researchers combine images from MRI and CT (computerized tomography) scans with physiological
measurements of the animals' neural responses to sound. The data may help to
understand how cephalopods detect predators and prey or use other
acoustic cues in ocean environments.
